I don't buy cage eggs if at all possible. I've personally seen how messed up those battery cage farms are. I'm no vegetarian, but there are better ways of getting eggs than that. I'm willing to pay a little more to put the birds through less suffering.
Don't get me wrong - I'm not PETA member. I'm no animal-worshipper. I am a humanist and a human-centrist and a fanatical defender of humanity as the only species capable of science. But although I do believe animals are less intelligent (and therefore, less capable and of lesser importance than humans) I do know that they can feel pain. You stick a fork into a Chicken, it will react. You deprive a chicken of water, and it will be distressed. You stick it in a goddamn cage barely large enough to hold it and literally lock its head in place so that it can do nothing but feed and lay eggs, and I can guarantee you that chicken will be stressed the hell out.
Yeah, Chickens aren't human. Not even close to human. Yeah, they don't deserve the same rights as humans. But that doesn't mean they don't deserve any rights. They deserve to have some freedom of movement. Some air. Some sun.
If you're going to eat eggs, don't buy cage eggs. No animal, except for many flies, and some other insects, deserves the cage treatment.
Again - I'm not PETA person. I'm not a vegetarian. But I do know that animals can feel pain and distress. If they couldn't they never would have survived the wild. Biologically, they have nerves, and they can feel with those nerves. Once again - if you stick a fork into a live chicken, it'll react to that fork. It feels it.
Pay slightly more so that battery cage farming ends. Because that stuff's messed up.
